Abstract (en)
[origin: WO2019228644A1] Fluid pump (10; 10') for a motor vehicle, with a driving means (18), a pump wheel (12) being co-rotatably connected with the driving means (18) by a rotor shaft (16) and a shaft bearing system (22; 22') for the rotor shaft (16), comprising a static bearing receptacle (24; 24') with a radially inwardly directed axial support flange (32) and two floating ball bearings (28, 30; 28', 30') both fixed to the radial outside of the rotor shaft (16) and provided axially shiftable within the bearing receptacle (24; 24'), wherein a first ball bearing (28; 28') is positioned at a first axial side of the support flange (32) and a second ball bearing (30; 30') is positioned at a second opposite side of the support flange (32), wherein an outer race (28c; 28c') of the first ball bearing (28; 28') is in touching axial contact with the support flange (32) and an outer race (30c; 30c') of the second ball bearing (30; 30') is axially preloaded away from the support flange (32) by a preload spring (36), wherein each ball bearing (28, 30; 28', 30') is provided with at least one elastic support ring (34) radially surrounding the outer race (28c, 30c; 28c', 30c') of the ball bearing (28, 30; 28', 30'), and wherein both ball bearings (28, 30; 28', 30') are radially supported within the bearing receptacle (24; 24') only by the support rings (34).
